Phasefale Three Phase Motor Protector

Three phase motors can fail due to electrical supply problems including loss of phase, low supply voltage, intermittent supply or damaged control contacts. All too commonly the loss of a phase is beyond your control and occurs at a critical time. The consequence is a burnt out motor which at least requires re-winding, but the cost of a failure can be much more; Cost to remove and re-install the motor for repair. Possible loss of stock and profits. Loss of management time.

The MP15 protects motors from all the above and is fully automatic in operation. Evolved since 1971, the MP15 employs advanced microprocessor technology, and is built with surface mount technology for improved reliability. With these advanced features it is compact and economical can be used on individual motors from 1Hp and above on 415-450V AC 50-60Hz.

The MP15 also includes timing functions which can eliminate additional circuitry in refrigeration applications and further improve the economics of motor protection. The MP15's is suitable for all sizes of three phase motors and therefore has many applications.

Operationally the MP15 signals system status with the single multi coloured LED:

• Green (running OK)
• Amber ( previous memory fault)
• Red ( fault-motor not running)

MP15: Three Phase, Octal Based, Fault memory, Adjustable start delay
